SPECIFICATION forming part of Letters Patent No. 779,317, dated January 3, 1905.

' Application filed March 29, 1904. Serial lilo. 200,576.

To all whom, w may concern;

Be it known that I, SAMUEL E. Ron, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved lVindow-Sash, of which the following is a full, clear, and exact description.

This invention relates to that class of sashes which are hung not only to slide vertically in the window-frame, but also to swing around a horizontal axis.

The object of the present invention is to provide improved means for mounting the sashes in this manner, so that they may be readily swung into open position and so that when closed they will make an absolutely airtight connection.

A further object is to provide means by which the sash when closed will be held securely in this position and will not be allowed to open except by the application of a positive pressure on the sash, thus avoiding accidental opening thereof.

1 attain these ends by providing sliding stiles, between which the sash is carried and to which the sash is connected by means of pivot-pins. Springs are employed yieldingly to press the stiles against the sides of the sash, and peculiarly-formed interlocking devices are provided between the stiles and sash, so that not only is a practically air-tight connection efiected between the sash and stiles when the sash is closed, but the sash is held in closed position against all ordinary accidental pressure and only allowed to open upon the application of manual pressure applied to open the sash.

Various other features of major and minor importance are employed, and all will be fully set forth hereinafter.

The following is an exact description of one example of my invention, whilethe claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a fragmentary perspective view of a window-sash. Fig. 2 is a fragmentary perspective view of one of the stiles, Fig. 2 illustrating the stile as though it were given a half-turn from the shaft and placed alongside of the same. Fig. 3 is a horizontal section showing the stile and sash in their proper relation, this section being taken on the lines 3 3 of Figs. 1 and 2; and Fig. 4 is a horizontal section of the stile and sash on the lines 4 4: of Figs. land 2.

10 indicates a window-frame provided with the guides 1O 10, intended, respectively, for the lower and upper sashes. The sashes comprise a rectangular frame 11 and glass 12, as shown. In accordance with the construction shown in Fig. 3 two sashes are provided; but it is clear that the invention is not limited to the number of sashes employed or to the special form of the sash.

14 indicates the stiles, which are two for each sash and which are located,respectively, at the vertical sides of the sashes and run in the guides in the window-frame. Said stiles may, if desired, be hung on weighted chains 15, so as to balance the sashes. (See Fig. 2.) The sashes are pivotally supported between their respective stiles by means of horizontal pins 16,which are located, preferably, midway the vertical length of the sashes and pass through the stiles and the facing-plates 17, secured to the frames 11 of the sashes. The stiles 14 may also beprovided with facingplates 18, through which the pins 16 pass, and both of said plates are let into the adjacent surfaces of the sash-frame and stiles, as shown best in Fig. 4. The pins 16 have heads 16 projected into cavities 11 in the sashframes 11, and springs 19 are provided, said springs lying in the cavities 11 and bearing between the heads of the pins 16 and the faceplates 17 The springs 19 areexpansive and act,therefore,to draw the stiles tightly against the vertical sides ofthe sashes in the manner indicated in Figs. 3 and 4.

Secured to each stile 14, below the pins 16 and at one side of the vertical line in which said pins lie, is a cleat 20, constructed with an overhanging beveled inner edge 20, and each stile carries above this pin 16 and at the opposite side of the vertical line in which said pin lies a cleat 21, constructed with an overhanging beveled end 21. The inner ends of the cleats 20 and 21 lie in the horizontal line of the pins 16, and are beveled, as indicated at 20" and 21". Corresponding but oppositelysituated cleats 22 and 23 are fastened to the sash-frame 11, said cleats having their inner edges formed with overhanging bevels 22 and 23 and their inner ends beveled, as indicated at 22 and 23 These cleats 20, 21, 22, and 23 constructed and arranged as described, formfirst a thoroughly secure connection between the sashes and stiles and also a means for holding the sashes securely yet releasably in closed position. In attaining these ends the overhanging beveled portions 21, 22, and 23 interlock, as indicated in Fig. 3, and in attaining the second of these results the beveled portions 20 21 and 23 match together, as indicated in Fig. 4, and owing to the coaction of the springs 19 said beveled portions resist any opening movement of the sashes until there is applied to the sash an opening force superior to the strength of the springs. hen this takes place, the beveled surfaces 22 and 23 will ride, respec tively, over the beveledsurfaces 20 and 21 The stiles 14: will be pushed sidewise, the springs 19 compressing to allow this movement, and the sash will then be free to swing into or approaching a horizontal position. The friction between the cleats 20 and 21 and the cleats 22 and 23, caused by the pressure of the springs 19, will hold the sashes in open position until sufiicient force is applied .to overcome this friction.

Fig. 3 shows the sash when it is closed, and in this adjustment the stiles 14 are separated from the bottom walls of the guide in which the stile runs. When, however, the sash is opened, the stiles are pressed outward and caused to more closely approach, if not actually to contact with, the bottom walls of the sash-guides.

When the sash is closed, the peculiar interlocking of the cleats 20 23 effects between the sash and stile a connection which is for all practical purposes hermetic, and it follows that by making the stiles tight against the side walls of the guides 10 or 10" in the windowframe the entire window structure will be rendered air-tight, notwithstanding that the sashes may be moved vertically to open or close the window, as in the ordinary construction, and may also be moved on their horizontal pivots so as to open the window to the full extent of the area of the window-frame.

The invention may be applied to windows of any sort.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence 1 consider myself entitled to all such variations as may lie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of astile, a sash pivoted thereto, said parts being capable of relative movement along the pivot, two cleats secured to the stile respectively above and below the pivot and respectively on opposite sides of the vertical line in which the pivot lies, two corresponding cleats secured to the sash, said cleats having overhanging longitudinal edges coacting substantially as described to form an air-tight connection between the stile and sash, and said cleats also having beveled or camshaped portions coacting to separate the stiles and sash as the sash is turned.

2. The combination of a stile, asash, a pivotpin pivotally mounting the sash-on the stile, said parts being capable'of relative movement along the axis of the pin, a spring holding the stile and sash yieldingly engaged, and interengaging cleats carried by the stile and sash to effect an air-tight connection between the two, said cleats having means for spreading the stile and sash upon the pivotal movement of the sash, whereby to disengage said cleats.

3. The combination of a stile, a sash pivoted thereto, said parts being capable of relative movement along the axis of the pivot, and cleats secured respectively to the stile and sash and adapted to engage each other to form a secure connection between the stile and sash, said cleats having cam-shaped portions coac'ting to separate the sash and stile as the sash is turned.

4. The combination of astile, a sash, a pivotpin pivotally mounting the sash on the stile, said parts being capable of relative movement around the axis of the pin, and cleats secured to the stile and sash and adapted to engage each'other to effect a tight connection between the stile and sash, said cleats having means for spreading the stile and sash upon the pivotal movement of the sash.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
